STATE TRUE 0R FALSE IN THE FOLLOWING QUESTIONS 1) 2) 3) 4) 5) When a data table has high dimension, it means the number of records is huge. If the imbalance sample issue is not solved, the estimated model will likely predict the rare event better than the non-rare event. The size of the training set must at least equal to the size of the validation set. Validation data set is required by both directed and undirected data mining task. When two models are of similar validation performance, the optimal model is chosen based on the degree of model complexity
